Ex-Premier Leeague footballer Ian Wright has spoken of his disgust after Mario Balotelli was racially abused on Twitter for mocking Manchester United's defeat at Leicester City.

Hate-filled social media users targeted the Liverpool and Italy striker after he goaded the Red Devils fans with a tweet which simply read: 'Man utd ... LOL.'

One vile tweeter, known only as iMonko, wrote: "Monkey, monkey, monkey, monkey, monkey."

While another particularly disgusting tirade read: "@F**k you Mario you f*****g n****r. Go eat some bananas and get ebola you dirty monkey."

The sickening abuse was labelled 'disgraceful' by the former Arsenal and England star .

He wrote on Twitter: "Cannot believe the abuse @FinallyMario took! In this day and age. Over a comment about a game of football. Disgraceful."

Many other Twitter users came to Balotelli's defence yesterday and some screengrabbed and re-tweeted some of the vile messages, and forwarded them on to police.

The football equality group Kick It Out said in a message on Twitter that it was aware of the racist tweets directed bat Balotelli and that it would be reporting the matter to the authorities.

Merseyside Police has since said it is investigating.

The force posted a message on Twitter, which read: "We can confirm officers are looking into offensive comments made on Twitter about Mario Balotelli earlier today."

Asked if they were launching an investigation, a Merseyside Police spokesman said "yes, we are", adding: "As far as I am aware there have been no complaints but we have been made aware of it by a number of press inquiries."

Manchester United led 3-1 at half-time before conceding four second-half goals in 21 minutes against newly-promoted Leicester.

Balotelli was joined by others from across the world of football left in disbelief at United’s latest horror show.

Former Arsenal midfielder and Sky Sports pundit Paul Merson said: "Man Utd a Gillion miles away from winning the title."

TV presenter and Arsenal fan Piers Morgan tweeted: "To be fair to Van Gaal, he has brought in a new era at United - they're worse than I've ever seen them."

And Match of the Day presenter and former Leicester striker Gary Lineker simply said: "S*** on Man United!"

The controversial 24-year-old, born to Ghanaian immigrants in Italy before being fostered by an Italian family, suffered from racism throughout his career in Italy, and was even racially abused by fans at a national team training camp ahead of this summer's World Cup.

In April 2009, Inter president Massimo Moratti said he would have taken his team off the pitch following the abuse the 18-year-old received at Juventus.

And during the summer of 2009, he had a banana thrown at him in Rome in the city centre.

In an interview published in GQ magazine in July he said: "They (the abusers( aren't used to seeing people who are different, not white, who act not as rebels but normally.

"I think what the ignorant people don't like is that people who are different are allowed to act that way.

"These stupid people, they get angry with me, they say horrible things, but I haven't done anything different from other people.

"I have made mistakes, like everyone does, and I have always paid for my mistakes.

"I think that if I was white maybe some people would still find me irritating or annoying but it wouldn't be the same.

"Absolutely not.

"Jealousy is a horrible thing, but when this jealousy is towards people who are different from the majority, and who maybe also have more than you, then it becomes anger, it becomes rage, and that's the overt racism."
